Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: Metabo HPT EC914S 'The Tank' (6-Gal, 1.3 HP, 200 PSI) (8,343W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| DeWalt DWFP55126 (6-Gal, 0.9 HP, 165 PSI) | 1,200W | 6,180W | Safe | ~3.6h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1200W from OEM rated amps (10A × 120V). **Estimated startup surge:** 6180W at 5.15x running (proxy from CRAFTSMAN OEM data for comparable 6-gallon pancake compressor — no DeWalt starting watts published). **Voltage:** 120V AC. Oil-free pump, 0.9 HP universal motor, 165 PSI max. Field note: The DWFP55126 is the best-selling pancake compressor in the US. Despite the modest 1200W running draw, the ~6180W startup surge means most power stations under 3000W surge capacity will trip on compressor restart. Size for surge first, not running watts. Can a portable power station run the DeWalt DWFP55126? Only if your power source can supply at least 1200W continuous and approximately 6180W surge at 120V. The compressor startup surge is the main limiting factor, not the running watts. | |||||
| CRAFTSMAN CMEC6150 (6-Gal, 0.8 HP, 150 PSI) | 1,320W | 6,800W | Safe | ~3.3h | OEM Verified |
Show expert analysisTechnical: **Running load:** 1320W (OEM published). **Startup surge:** 6800W (OEM published, 5.15x running). **Voltage:** 120V AC. Oil-free pump, 0.8 HP motor, 150 PSI max. This is the only variant in this set with OEM-published starting watts. Field note: The CRAFTSMAN OEM data reveals a critical insight: pancake compressors surge at over 5x running watts — far more than the 3x NEC assumption used for many motor loads. This is because the compressor must overcome residual tank pressure on restart. Always size for the 6800W surge, not the 1320W running draw. Why does this compressor need so much more starting power than running power? The motor must overcome compressed air resistance in the tank at startup. CRAFTSMAN rates this model at 6800W starting versus 1320W running — a 5.15x ratio. Most power stations under 3500W surge will fail to start this compressor. | |||||
| Metabo HPT EC914S 'The Tank' (6-Gal, 1.3 HP, 200 PSI) | 1,620W | 8,343W | Safe | ~2.7h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 1620W from OEM rated amps (13.5A × 120V). **Estimated startup surge:** 8343W at 5.15x running (proxy from CRAFTSMAN OEM data for comparable 6-gallon pancake compressor — no Metabo HPT starting watts published). **Voltage:** 120V AC. Industrial motor, 1.3 HP, 200 PSI max — the most powerful unit in this set. Field note: The EC914S draws 35% more running watts and has an estimated 8343W surge — this is the hardest-to-run pancake compressor in the set. Most consumer power stations cannot start it. Its 200 PSI max and 4.0 SCFM output make it a jobsite-grade tool that demands jobsite-grade power. Why does the Metabo HPT need so much more power than the DeWalt? At 1.3 HP versus 0.9 HP, the EC914S delivers 54% more air flow and 21% higher max pressure. That extra performance requires 1620W running and an estimated 8343W startup surge — significantly more than entry-level 0.8-0.9 HP compressors. | |||||

Generator Insights
With 12000 watts of surge capacity, this system can handle typical startup loads for central air compressors, well pumps, and other motor-driven equipment common in residential settings. The 6000-watt continuous rating supports sustained operation of multiple high-draw appliances simultaneously. The 6144 Wh capacity provides meaningful runtime for essential circuits during grid outages.
This unit uses lithium iron phosphate (LFP) chemistry, known for stable thermal behavior in stationary storage applications. The system is designed with internal protections typical of grid-tied and off-grid battery platforms. Source: EcoFlow DELTA Pro Ultra User Manual (manufacturer documentation).

Spec-Based • No GuaranteesTechnical Breakdown
Running range: 1200W to 1620W depending on motor size (0.8-1.3 HP). Surge range: 6180W to 8343W — pancake compressors surge at approximately 5x running watts due to compressed air resistance on restart. Voltage: 120V AC for all models.
Expected Behavior
Estimated runtime: ~2.7h. Compressors cycle between cut-in and cut-out pressure, creating repeated surge events during use. Daily energy consumption at 1 hour use ranges from 600 to 1215 Wh depending on model and duty cycle. Recommended duty cycle is 50-75% (30-45 minutes per hour max).
Field Note
Compressor startup surge is the primary compatibility bottleneck — not running watts. A power station rated at 2000W continuous but only 3000W surge will fail to start any compressor in this set. OEM data shows pancake compressors surge at over 5x running, far exceeding the 3x often assumed for motor loads.
